United States Patent WIRE STRIPPER ATTACHMENT FOR PLIERS Robert F. Cook, Jr., Tulsa, Okla.

Application August 28, 1952, Serial No. 306,793

2 Claims. (Cl. 819.5)

The invention relates to wire stripper attachments for the jaws of pliers, particularly the side cutter type, and has for its object to provide stripper attachments which may be applied to each jaw of the pliers without modifying in any way the construction of the plier jaws.

A further object is to provide stripper members detachably attached to the plier jaws on one side thereof, and opposite the side cutters of the jaws and the attachments comprising stripping members having mwardly extending portions disposed in the recesses of the jaws adjacent the hinging point of the pliers and holding members arching the outer sides of the jaws and hooked over the jaws, and forming means for rigidly holding the stripper members on the jaws for a stripping operation, and at the same time not interfering with the use of the pliers for various purposes, and the side cutters.

A further object is to provide the stripper members with a plurality of wire receiving grooves of difierent size, and stripping blades in connection with said grooves, and notched to strip different size wires.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:

Figure 1 is a perspective view of a pair of pliers showing the stripper members applied to the jaws thereof.

Figure 2 is a side elevation of the pliers and stripper.

Figure 3 is a vertical transverse sectional view taken on line 3-3 of Figure 2.

Figure 4 is a vertical transverse sectional view taken on line 4-4 of Figure 2 looking in the opposite direction.

Figure 5 is a collective detail perspective view showing one of the plier jaws, and the stripper element in position to be applied to the jaw.

Figure 6 is a front elevation of the pliers showing a modified form of stripper attachment for cutting the armor or covering of a duplex wire.

Referring to the drawing, the numeral 1 designates cross handles of a pair of pliers hingedly connected together at 2, and 3 the plier jaws. The inner sides of the jaws 3 are provided with conventional recesses 4 and with side cutters 5, conventional structure. It will be noted that the recesses 4 are angularly shaped in cross section, and this angular shape forms part of the holding means for the stripper attachments 6, which attach ments extend outwardly from the sides of the jaws 3, clearly shown in Figure 1, and in a position where they will not interfere with the normal use of the pliers and side cutters during a wire cutting or manipulating operation. The members 6 are provided with extension arms 7, which extend into the recesses 4 and conform to the shape thereof.

Stripper members 6 are further anchored to the sides of the jaws 3 by clamping plates 8 secured to the members 6 by screws 9, and the clamping plates 8 terminate in hooked ends 10, which hook over the opposite sides of the jaws 3, therefore it will be seen that the stripper mem- "ice bers are rigidly attached to the jaws in a position whereby they will register with each other, when the jaws are closed, for clamping a wire to be stripped in the selected grooves 11 of the members 6. Grooves 11 are of different size for ditlerent size wires, and the number of grooves may be varied as desired.

Secured to the forward ends of the members 6 by means of screws 12 are stripper plates 13, of the blade type, having stripper notches 14 corresponding to the grooves as to size, therefore it will be seen that when a stripping operation is desired, it will be necessary only for the operator to place a wire in the selected groove 11, close the jaws of the pliers, which operation will cause the notched blades to cut the armour of the wire transversely, without severing the wire, and then the operator pulls on the wire, and this will strip the armour or covering from the wire as desired.

In Figure 6, wherein a modified form of device is shown, the structure is the same as in Figure 1, except the members 6 are provided with registering transversely enlarged grooves 15 for the reception of a duplex wire to be slit between the wires by longitudinally extending splitting blades 16. The blades 16 are clamped in kerfs 17 of the members 6 by screws 18. i

From the above it will be seen that stripper attachments are provided for the jaws of a pair of pliers, which attachments may be easily and quickly applied to the pliers without modifying the construction of the pliers, and when the attachments are in position on the jaws of the pliers will not interfere with the normal use of the pliers or the side cutters of the pliers.

Referring to Figure 2, it will be noted that the rear portion of the stripper members 6 are cut away to form a V-shaped arrangement 19 which will allow a wire to be easily passed through and between the plier jaws transversely to be severed by the side cutters 5. It will also be noted that the stripper members 6 are formed integral with their extensions 7, hence it will be seen that these parts can be made as a single unit.

The invention having been set forth what is claimed as new and useful is:

1. The combination with cooperating jaws of a pair of pliers, of wire stripping attachments engaging the sides of the jaws on the same side of pliers, wire stripping blades carried by said attachments and adapted to register when the jaws are closed, clamping plates carried by the attachments and arching the outer sides of the jaws, the ends of said plates terminating in flanges engaging the opposite sides of the jaws from the attachments, said attachments having integral members extending between the jaws and disposed in recesses in the inner sides of the jaws at points spaced inwardly from the outer ends of the jaws.

2. The combination with cooperating jaws of a pair of pliers, said jaws having recessed inner engaging faces; of a wire stripping attachment comprising a pair of body members engaging the sides of the jaws on the same side of the pliers, wire stripping blades carried bv the members and adapted to register when the jaws are closed, clamping plates detachably affixed to the members and projecting laterally therefrom and extending over the outer faces of the jaws, said clamping plates having flanges engaging the sides of the jaws opposite from the body members and integral lateral extensions on the body members disposed in the recesses in the inner faces of the jaws.
